Galaxy S7 users blame new OS update for causing trouble

SEOUL -- Samsung Electronics faces fresh complaints from users of its old Galaxy S7 after a new operating system (OS) was updated. There has been no official reaction with service centers citing mainboard malfunctioning.

More than 130 users of Galaxy S7 released in early 2016 created an online community called "Galaxy S7 Mainboard Defect" this week, claiming that their phones crashed after a new OS update in June.

"Today, my phone started to heat up and it struggled to reboot itself over and over again," Jadoo, a community member, said in a post. "I turned it off after it tried to reboot itself for two hours." Community members insisted their phones have intermittently frozen and heated up to become "brick", a term used in South Korea for broken IT hardware.

Because the price for fixing the mainboard was about 200,000 won ($179), some S7 users gave up visiting Samsung's service centers and chose to buy a new one. LG Electronics has fixed similar mainboard defects for free.
